create nested JSON object in php?
(7 answers)
Closed last year.
I have to comunicate with some API which expect JSON.
Until now I was fine because I needed just simple json so I just create array like this:
$data = array (
"firstName" => "TEXT1",
"lastName" => "TEXT2",
"license" => "TEXT3",
"password" => "TEXT4",
"username" => "TEXT5"
);
And after that just simple
$data_string = json_encode($data);
So final JSON looks like:
{
"firstName": "TEXT1",
"lastName": "TEXT2",
"license": "TEXT3",
"password": "TEXT4",
"username": "TEXT5"
}
However now I have to change it a bit and I am confuse, my new JSON shoud looks like:
{
"contact": {
"city": "New Yourk",
"email": "my#mail.com",
"phone": "777888999",
"postCode": "07101",
"street": "Street N. 12"
},
"enabled": true,
"firstName": "Robert",
"lastName": "Exer",
"username": "login#login.com",
"license": "text",
"password": "text"
}
As you can see it is basicly just added contact part. I was thinking how I can do this but only think I found was something like to insert array to existing $data array and then json_encode this but this will not give me a contract: at start.
Of course there is possible to do it some other way like create one json and then another and hardly connect string and so on. But i believe there have to be some better way how to do things like this.
I apprciate any advise:)
Just put an array in the value of contact:
$data = array(
'contact' => array(
'city' => 'New York',
'email' => 'my#mail.com',
//...
),
'enabled' => true,
'firstName' => 'Robert',
'lastName' => 'Exer',
//...
);
$data_string = json_encode($data);
An array can contain another array, which will be encoded as a separate object inside the previous object:
$data = array (
"contact" => array(
"city" => "New Yourk",
"email" => "my#mail.com",
"phone" => "777888999",
"postCode" => "07101",
"street" => "Street N. 12"
),
"enabled": true,
.. etc
);

I'm getting via url querystring variables like:
myserver_state=1&myserver_running=2&myserver_mem=3
Currently i'm adding to an existing json like:
{
"key1": "1",
"key2": "2",
"key3": "3",
"myserver_state": "1",
"myserver_running": "2",
"myserver_mem": "3"
}
And i really want it like this:
{
"key1": "1",
"key2": "2",
"key3": "3",
"myserver": {
"state": "1",
"running": "2",
"mem": "3"
}
}
I'm using this to load them:
$formdata = array(
'state'=> $_POST['state'],
'uassip'=> $_POST['uassip'],
'uassipport'=> $_POST['uassipport'],
'c_uacminrtpport'=> $_POST['c_uacminrtpport'],
'c_uacmaxrtpport'=> $_POST['c_uacmaxrtpport'],
'c_cps'=> $_POST['c_cps'],
'c_totalcalls'=> $_POST['c_totalcalls'],
'c_maxchannels'=> $_POST['c_maxchannels'],
'c_duration'=> $_POST['c_duration'],
'c_to'=> $_POST['c_to'],
'c_uacxml'=> $_POST['c_uacxml']
);
echo "fromdata: <br>"; echo var_dump($formdata) . "<br><hr>";
if(file_put_contents('testconfig.json', json_encode($formdata) )) echo 'OK';
else echo 'Unable to save data in "testconfig.json"';
Many thanks!
EDIT:
following comments i tried:
status.php?server1[current_state]=10
this actually works to:
"c_uacxml": "telnyx-uac-invite-ok.xml",
"server1": {
"current_state": "10"
}
}
Which is great, BUT, if i then want to add an element like this:
status.php?server1[current_mem]=1
This actually REPLACES the whole server1
"c_uacxml": "telnyx-uac-invite-ok.xml",
"server1": {
"current_mem": "10"
}
}
and i lose the already existing current_state
Just use multidimensional array within your URL like:
test.php?key1=1&key2=2&myserver[state]=1&myserver[running]=2&myserver[mem]=3
so easy script
<?php
echo '<pre>';
echo json_encode($_GET, JSON_PRETTY_PRINT);
will give you
{
"key1": "1",
"key2": "2",
"myserver": {
"state": "1",
"running": "2",
"mem": "3"
}
}
of course, if required you can use also POST request with the same naming rules.
in order to create a nested JSON object, you need to create an array within an array.
E.g.
$example = [
'key1' => 'foo',
'key2' => 'bar',
'key3' => [
'subkey1' => 'foo',
'subkey2' => 'bar',
],
];
When running it through json_encode(), it will result in
{
"key1": "foo",
"key2": "bar",
"key3": {
"subkey1": "foo",
"subkey2": "bar"
}
}
Also it's not necessary to load form data like this –
$formdata = [
'state' => $_POST['state'],
'uassip' => $_POST['uassip'],
'uassipport' => $_POST['uassipport'],
'c_uacminrtpport' => $_POST['c_uacminrtpport'],
'c_uacmaxrtpport' => $_POST['c_uacmaxrtpport'],
'c_cps' => $_POST['c_cps'],
'c_totalcalls' => $_POST['c_totalcalls'],
'c_maxchannels' => $_POST['c_maxchannels'],
'c_duration' => $_POST['c_duration'],
'c_to' => $_POST['c_to'],
'c_uacxml' => $_POST['c_uacxml'],
];
Since the $_POST already contains a structure that you are trying to recreate. You can simply assign the post data to a new varaible.
On another note, I highly recommend you to check out PSR PHP standards, they will greatly help to improve code readability and your code structure :) https://www.php-fig.org/psr/

How to add square braces around subarray data inside of a json encoded string?
(3 answers)
Closed 6 months ago.
this is the json i have to produce
{
"email": "example#example.com",
"campaign": {
"campaignId": "p86zQ"
},
"customFieldValues": [
{
"customFieldId": "y8jnp",
"value": ["18-29"]
}
]
}
if i use
$data = [
"email" => $_POST['mail'],
"campaign" => [
"campaignId" => "4JIXJ"
],
"customFieldValues" => [
"customFieldId" => "y8jnp",
"value" => ["18-29"]
]
];
and i do json_encode($data)
value is an object, but it should be an array with a single element. Somehow json_encode treats it as an object. Can i force it to treat it as an array with a single element ?
Thanks in Advance

At the moment, you have a single array with 2 elements, instead of an array with a single element of a sub-array. In order to get the json in the first section, you need to add another array level.
$data = [
"email" => $_POST['mail'],
"campaign" => [
"campaignId" => "4JIXJ"
],
"customFieldValues" => [
[
"customFieldId" => "y8jnp",
"value" => ["18-29"]
]
]
];
That will give you this:
{
"email": null,
"campaign": {
"campaignId": "4JIXJ"
},
"customFieldValues": [
{
"customFieldId": "y8jnp",
"value": ["18-29"]
}
]
}
if there is one single element in the array the json_encode will treat is as an object and the key of the object is the index of the array
to treat it as an array you can use array_values(<your_array>)
I know this has been asked before, however nothing seems to work
I have following json output:
"coordinates": [
"18.366466",
"29.898110"
]
However, the output I want is:
"coordinates": [
18.366466,
29.898110
]
$coordinates = array($result->lat, $result->lng);
$output[$i++] = array(
"type" => "Feature",
"geometry" => array("type" => "Point",
"coordinates" => $coordinates),
"properties" => array(
"ID" => $result->id,
"icon" => $result->icon,
"tags" => $tagsForJson,
"title" => $result->title,
"description" => $result->description));
Trim, str_replace and all of those functions are not working
Thank you!
What you're looking to do is type-cast this data into an float.
After preparing (trimming, etc) the string with the numbers, you can do something like this:
$coordinates = array((float)$result->lat, (float)$result->lng);
Or to cast the whole array at once, more simply you could utilize array_map and floatval
$coordinates = array_map('floatval', $coordinates);
I have a PHP variable I need to convert to JSON string.
I have following PHP code:
$username="admin";
$password="p4ssword";
$name="Administrator";
$email="myname#smsfree4all.com"
$params=compact('username', 'password','name','email', 'groups');
json_encode($params);
This works fine. But what I am not sure about is how do I encode the properties in PHP with nested key value pairs shown below:
{
"username": "admin",
"password": "p4ssword",
"name": "Administrator",
"email": "admin#example.com",
"properties": {
"property": [
{
"#key": "console.rows_per_page",
"#value": "user-summary=8"
},
{
"#key": "console.order",
"#value": "session-summary=1"
}
]
}
}
What is this with # before key value?
Something like this should do it
$username="admin"; //more variables
$params=compact('username' /* more variables to be compacted here*/);
$params["properties"] = [
"property" => [
[
"#key" => "console.rows_per_page",
"#value"=> "user-summary=8"
],
[
"#key"=> "console.order",
"#value"=> "session-summary=1"
]
]
];
echo json_encode($params);
The manual has more examples you can use
Notice that:
A key~value array is encoded into an object
A regular array (array of arrays here) is encoded into an array
Those are all the rules you need to consider to encode any arbitrary object
Something like this perhaps?
$properties = [
'property' => [
['#key' => 'console.rows_per_page', '#value' => 'user-summary=8'],
['#key' => 'console.order', '#value' => 'session-summary=1']
]
];
It's difficult to tell what you're asking.
You can nest in PHP using simple arrays, very similar to JavaScript objects:
$grandparent = array(
"person1" => array(
"name" => "Jeff",
"children" => array(
array("name" => "Matt"),
array("name" => "Bob")
)
),
"person2" => array(
"name" => "Dillan",
"children" => array()
)
);
I don't work with php much and I'm a little fuzzy on object creation. I need to make a webservice request sending json and I think I have that part covered. Before I can submit the data I need to create a nested object. I was assuming this would be trivial based on my experience with ecma based scripting languages, but I'm finding the syntax to be difficult to navigate. The object I want to create is below.
{ "client": {
"build": "1.0",
"name": "xxxxxx",
"version": "1.0"
},
"protocolVersion": 4,
"data": {
"distributorId": "xxxx",
"distributorPin": "xxxx",
"locale": "en-US"
}
}
I've seen a lot of examples of flat objects, but I haven't found a minimal example for a nested object yet. What would be the php syntax for the object above? Is this an unusual thing to do in php?
this JSON structure can be created by following PHP code
$json = json_encode(array(
"client" => array(
"build" => "1.0",
"name" => "xxxxxx",
"version" => "1.0"
),
"protocolVersion" => 4,
"data" => array(
"distributorId" => "xxxx",
"distributorPin" => "xxxx",
"locale" => "en-US"
)
));
see json_encode
Hey here is a quick trick to manually convert complex JSONs into a PHP Object.
Grab the JSON example as you have:
{ "client": {
"build": "1.0",
"name": "xxxxxx",
"version": "1.0"
},
"protocolVersion": 4,
"data": {
"distributorId": "xxxx",
"distributorPin": "xxxx",
"locale": "en-US"
}
}
Search-Replace { to array(
Search-Replace : to =>
Search-Replace } to )
Done.
User array to get the correct format and then call echo json_encode(array)
array( "client" => array(
"build" => "1.0",
"name" => "xxxxxx",
"version" => "1.0"
),
"protocolVersion" => 4,
"data" => array(
"distributorId" => "xxxx",
"distributorPin" => "xxxx",
"locale" => "en-US"
))
$client = new Client();
$client->information = new Information();
$client->information->build = '1.0';
$client->information->name = 'xxxxxx';
$client->information->version = '1.0';
$client->protocolVersion = 4;
$client->data = new Data();
$client->data->distributorId = "xxxx";
$client->data->distributorPin = "xxxx";
$client->data->locale = "en-US";
Perhaps something like the above? The client would hold two objects. Information and Data.
Edit
Using json_encode, you would create this object as an array in PHP..
$clientObj = array('client'=>
array( array('build'=>'1.0','name'=>'xxxx', 'version'=>'1.0'),
'protocolVersion'=>4,
'data'=>array('distributorId' => 'xxxx', 'distributorPin' => 'xxxx', 'locale' => 'en-US')
);
print json_encode($clientObj);
We can also construct nested array and then do a json_encode to construct nested JSON.
For e.g:
{"User":
{"username":"test",
"address":"Posted value fro address field",
"location":{
"id":12345
}
}
}
Above output we can achieve by writing below php code:
<?php
$obj = array(
'username'=>$lv_username,
'address'=>$lv_address,
'location'=>array('id'=>$lv_locationId)
);
$data = '{"User":'. json_encode($obj) .'}';
echo $data;
?>
Hope it helps.
Use the in build function of PHP:
json_encode();
this will convert the array into JSON object.
You can use json_encode to encode a php array
http://php.net/manual/en/function.json-encode.php
$theArray = array('client'= array('build'=>'1.0',
'name'=>'xxxxx',
'version'=>'1.0'
),
'protocolVersion'=> 4,
'data'=> array('distributorId'=>'xxxx',
'distributorPin'=>'xxxx',
'locale'=>'en-US'
)
);
$theObj = json_encode($theArray);
hopefully this helps..
posted it, then seen loads of answers already! :|
